Read-out of Moisture probe

#1 Post by Ton_vN » 10 Feb 2017, 16:59

(Having some problems with humidity) to measure the moisture content in the bottom under the house, I fitted a 'fork'-probe, as shown at http://www.vannwnhzn.nl/esp8266a2_humtemp02.html
Analogue output from the prob's circuitboard to A0 of an ESP8266 WemosD1Pro, running ESPEasy (stable release R120).
IDX applied as valid for a related Virtual Device made in Domoticz for a Humidity Dummy.
Nominal scale for the ESP's ADC is 0 to 1024, and in practise the testmeasurements gave approx. 1024 (superdry) to 500 (superwet).
By formula (1024-%value%)/5 the measured value roughly converted in ESPEasy to 0 to 100, which could be an meaningful indicator for moisture contents.
Calling the ESP by its IP-address, the reading shows with a variable value between 0 and 50.
In Domoticz that value shows under Events/Current States for the related IDX.

So far OK, but Domoticz has put the read-out for the Virtual Device under category Temperature, and the value at the read-out firmly stays at 0.

Any similar experiences? Remedies to get a correct read-out in Domoticz?

Delete the Temperatur Sensor and chose percentage Typ sensor
Domoticz on Raspi 2 -- 14 ESP units (hacked Sonoff,NodeMCUs, Wemos, self-built units) running with RC140- Mega 2.0.0 dev8
